I did part a, it's 0.00889mol but can't figure out the molecular formula, please explain
II. Pre-Lab: 1. A sample of an unknown organic liquid is vaporized at 98.5 C in a flask with a volume of 278 mL. The ambient pressure is 742 torr. When cooled the condensate had a mass of 0.694 a) Determine the molar mass (78.0 g/mol) found to have an empirical formula of cniln b) In another experiment this unknown was Determine its molecular formula. 2. The vapor density of an unknown compound was found to be 3.85 g/L at 750 torr and 99.0 C. Determine the molar mass of the compound. (119 g/mol)
